The flame detector combines an ultraviolet detector that detects ultraviolet wavelengths and an infrared detector that detects infrared wavelengths. It is an ultraviolet/infrared composite detector. The UV/IR composite flame detector is sensitive only to certain relatively short wavelength segments, minimizing misoperation due to surrounding non-fire factors, and with high sensitivity sensors for minimal current consumption Maximum sensitivity is achieved, while the ability to judge the flame is enhanced, and the reliability of fire detection is improved.
Infrared flame detectors are suitable for use in smokeless liquid and gas fires, in open flames, and in detonation. For example: aerospace industry, hangars, aircraft repair yards, chemical industry, road tunnels, ammunition and explosives warehouses, paint factories, petrochemical companies, natural gas exploration and production companies, pharmaceutical companies, power stations, printing companies, flammable materials warehouses, etc. Other occasions where combustibles contain carbonaceous materials.
1. The infrared flame detector has a reset time of 10s during power-on. During this time period, the infrared flame detector does not respond to any fire alarm signal; after the power indicator light turns green, it can work normally; when the fire alarm occurs, the indication The light turns red.
2. When the infrared flame detector is connected to the system, its test work should be completed ahead of time: the flame is within the effective viewing angle range of the infrared flame detector, and the flame is continuously shaken or the flame is continuously shaken, so that the flame continuously flickers, and the alarm function and detection are observed. distance.
3, always check the infrared flame detector window glass surface is clean, must be wiped regularly. The infrared flame detector window glass is not clean, which will affect the sensitivity of the infrared flame detector. In severe cases, the infrared flame detector may not cause an alarm when a fire occurs.
4. It is strictly forbidden to open the cover when the infrared flame detector is energized; before cleaning, please stop the infrared flame detector temporarily, cut off the logic control function of the area or system that will be maintained, so as to avoid inaction alarm linkage.
5. It is forbidden to use the working power of the non-specified infrared flame detector to avoid damage to the infrared flame detector.
6, the infrared flame detector wiring must be reliable; infrared flame detector shield wire mesh connection shell, grounding should be firm.
7. The user should not disassemble the infrared flame detector at will, so as to avoid unnecessary loss.
